Giving 50 points for this and I'll give brainliest to one of the correct answers. 1. Blake randomly chose a letter from the alphabet. What is the probability that this letter has at least one line of symmetry, given that it is a consonant?

2. A card is randomly selected from a standard deck of playing cards. Find the probability that it is a face card, given that a black card is drawn.

3. A month of the year is randomly chosen. Find the probability that it has no more than 30 days, given that it starts with the letter A.

Please only answer if you know.

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d. what is the height of the tide after 93 hours?
